CO Detection in Idaho Hotels: What the Fire Code Requires, and When

The Idaho State Fire Marshal adopts the International Fire Code as the minimum standard for the whole state. Idaho Code 41-253(1) is the authority and IDAPA 18.08.01 is the rule that carries it, effective 1 July 2024. No city elects into this and none can drop out of it, which makes the fire code the instrument that decides most Idaho hotels.

Section 915 of the adopted code is the carbon monoxide provision, and Idaho left it alone. It reaches Group I-1, I-2, I-4 and R occupancies, and a hotel or motel is Group R-1. So a hotel built since the fire code took effect must have detection in the guest rooms that meet any of the conditions at 915.1.2 through 915.1.6, in every county in the state.

A hotel already standing when the code arrived is a different question, and Idaho answered it with two deletions. IDAPA 18.08.01.010 strikes Item No. 3 from IFC Section 102.1, the sentence that applies Chapter 11 to existing structures. Section 030 then adds to IFC 1101.1 the words "only, if in the opinion of the fire code official, they constitute a distinct hazard to life or property". Section 1103.9, the retrofit provision, therefore never arrives on its own. What survives is item 4 of 102.1, which reaches an existing building the fire code official considers a distinct hazard to life or property. For an older Idaho hotel the answer is that the local fire chief decides, and the operator can go and ask.

The building code is a second route and it does turn on the town. Idaho Code 39-4116 lets a local government choose whether to run a permit and enforcement programme, and one that runs a programme must adopt the International Building Code without variation. That election decides who reviews your plans and inspects your work. It has no bearing on whether the fire code applies to you.

Find the date the building was finished. That is the question that sorts Idaho hotels, and it sorts them the same way in Boise as in a county with no building department.

A hotel built since the fire code took effect is covered outright. IFC 102.1 item 1 applies the code to structures and conditions arising after its adoption, Section 915 sits inside that code unamended, and Group R-1 is a listed occupancy. Nobody has to elect anything for this to be true.

A hotel that predates the code is reached when the fire code official forms the opinion that it constitutes a distinct hazard to life or property. That is item 4 of IFC 102.1, and after Idaho's deletion of item 3 it is the only route left into an older building. An operator of a pre-code property who wants a straight answer should put the question to the official, because the opinion is the test and it is one person's opinion, not a threshold in a table.

The occupancy conditions are the model ones and Idaho did not touch them. Section 915 reaches a sleeping unit that holds a fuel-burning appliance or fireplace, one served by a fuel-burning forced-air furnace, one connected by a communicating opening to a space elsewhere in the building holding such an appliance, and one adjoining an attached private garage.

Where the building code also applies, its Section 915 is the same provision in a different code. The Idaho Board's amendments to the adopted building code touch Sections 305.2.3, 308, 310.4, 602.1.2 and Table 2902.1 and leave 915 alone, so an enforcing jurisdiction applies the same text the fire code already applies everywhere.

Work the building first, because for a hotel built since the code took effect the duty is already running and no phone call changes it. Map the fuel-burning equipment and the attached parking, list the guest rooms tied to each by a communicating opening or a duct, and put detection inside those rooms. Section 915.2.2 is written for sleeping units and says the detection goes in them; moving it out to the corridor is an exception available only where the room and its attached bathroom hold no fuel-burning appliance and no forced-air furnace serves them.

Then call the fire chief for the city, county or fire protection district where the property stands. Where no fire department covers the area, call the county sheriff, who holds the same role under Idaho Code 41-256(1). Ask which edition of the International Fire Code the office is enforcing and, if the hotel predates the code, whether the office treats the property as a distinct hazard under IFC 102.1 item 4. Write down the date and the name of whoever answers.

An operator of a pre-code hotel who gets "no" to that second question has a real answer and a dated record of it. What that answer does not do is change the equipment. A guest sleeping above a boiler is in the same room whether or not an official has formed an opinion about the building, and the detection that would have been required in a new hotel costs the same in an old one.

The specification is Section 915 of the International Fire Code as adopted by IDAPA 18.08.01, and in an enforcing jurisdiction the identical section of the 2018 International Building Code fixed by IDAPA 24.39.30.600.01 applies alongside it.

Detection belongs in the sleeping units meeting one of the four conditions, and Section 915.2 means that literally. 915.2.2 reads "Carbon monoxide detection shall be installed in sleeping units", with a single exception permitting the device outside each separate sleeping area, in the immediate vicinity of the unit, where the unit and its attached bathroom contain no fuel-burning appliance and no forced-air furnace serves them. 915.2.1, which places the device outside the sleeping area as its rule, governs dwelling units and not guest rooms. The model exceptions apply: where a fuel-burning forced-air furnace serves the units, a detector in the first room or area served by each main duct leaving the furnace, with automatic signal transmission to an approved location, stands in place of devices in the units; where the appliance is outside the units, detection is excused where no communicating opening connects them or where a detector sits between the appliance and the unit or on the ceiling of the appliance room.

Section 915 also permits a carbon monoxide detection system in place of individual alarms, which is the usual choice on a property large enough that per-room devices become a maintenance programme in themselves.

The State Fire Marshal holds the duty. Idaho Code 41-254(1) lists it first among the office's powers: to enforce the international fire code. Nothing in it is limited to particular occupancy classes and nothing waits on a local decision.

The map has no gaps in it, which is the part that separates the fire code from the building code here. Idaho Code 41-256(1) makes the chief of the fire department of every city, county and fire protection district an assistant to the State Fire Marshal in carrying out the code, and in areas where no organised fire department exists it gives that role to the county sheriff. Somewhere in Idaho a hotel sits in a county with no building department and no fire department, and the sheriff is still the officer charged with the fire code there.

Idaho Code 41-259 gives those officers the power to inspect buildings and premises in their jurisdiction, excepting the interior of private dwellings, private garages belonging to such residences, and buildings on farms of more than five acres. A hotel falls outside all of those exceptions. Where the officer finds a building endangering life through a violation of the International Fire Code, the section says the officer shall order it remedied or removed.

Alongside this, a city or county running a building permit programme reviews plans and inspects work under IDAPA 24.39.30, administered through the Division of Building Safety. An operator with hotels in several Idaho counties may deal with different building officials and the same fire code.

Idaho publishes a daily schedule and it escalates twice. Idaho Code 41-261 sets the penalty for failing to comply with an order at ten dollars for each day of the first week, fifty dollars a day for days eight through thirty, and one hundred dollars a day from the thirty-first, together with reasonable attorney's fees and costs awarded to the state or to the fire district that brought the action. The amounts are statewide and no ordinance sets them.

A second consequence sits in the rule. IDAPA 18.08.01.017 replaces IFC 110.4 so that a violator may be charged with a misdemeanor by prosecuting authorities where the violation is not resolved after written notice from the fire code official. Section 018 deletes IFC 112.4, so the model code's own penalty text is gone and the Idaho provisions are what remain.

In an enforcing jurisdiction the building side adds the familiar levers: a plan review that does not pass, a failed inspection, a certificate of occupancy withheld. Those reach new work. The fire code penalties reach the building as it stands.
